serai No. 504.892 lemma. (c1. 137-93) This invention is directed to animprovement in valves designed more particularly for usein connectionwith passenger car toilets.

Conventionally, toilets of this type include a.

valve for the control of the flushing o1 the water, 5 a handle memberfor operating the valve, and a connection whereby the handle memberwhenoperated also actuates the usual Idump pan.

Ordinarily, in the event that the packing renewal or repair of valveparts becomes necessary, l such operation can be only carried out by asubstantial dismantling or the. toilet proper; and furthermore as thevalves for different toilets will necessarily occupy .different relativepositions owing tothe location of the toilet, the valves l asconventionally constructed are necessarily for right or for left handapplication with respect to the toilet in order that the valve may bebest adapted to the position of the -particular toilet. The valve of thepresent invention is designed more particularly to overcome theobjections above noted and others equally apparent of the conventionalconstructions, and to this end the invention is designed to provide avalve in which the parts are readily separable for renewal or repairwithout the necessity of removing the toilet; a further object of theinvention being inthe provision of a valve which in itself and throughmere reversal of the valve body becomes readily appropriated for use ineither a right hand or llefthand position, thereby adapting a standardstructure of valve to any and all positions in which the valve maynecessarily be connected as restricted by the position of the-particular toilet.

A further object of the invention is the provision of a simple valveoperator which, while positive and effective in its action, isnevertheless simple and easy to operate and readily separable from thevalve structure in the event of repair or replacement of valve parts.

The invention is illustrated in the accompanyingd'rawing, in which:-

Figure 1 is a view in elevation illustrating the use oi the valve inconnection with a car toilet.

Figure 2 is an enlarged vertical sectional view partly in elevation o!the valve.

Figure 3 is a broken elevation of the valve body.

The improved valve includes a valvelbody 1 of barrel-like formthroughout. The respective ends of the body are exteriorly threaded, asat 2 and 3, and the body is interiorly formed adjacent the respectiveends with a circumferential enlargement, as 4 and 5, forming abruptshoul dersGand'LI/'herespectiveendsotthebody are thus of identicalformation. each including lthe exteriorly threaded portion, the interiorter- `minal enlargement, and the abrupt' shoulder formed v by theenlargement. The body v1 is formed with an outlet 8 arranged centrallyot 00 its length and appropriately formed for pipe connection, said bodyalso having a securing plate 9 integral with the body and diametricallyopposite the o'utlet 8, the plate 9 being secured to the body byappropriate reinforcing web -con- 85 struction to insure` that with thesecuring of the plate to a flxture, as through screw holes l0, the

`valve body will be properly supported.

explained. Each ring is formed in the flange portion with a conical seat15, and as the rings c' are disposed in the body with the flangeoutermost, the valve seats 15 are outwardly with respect to the body, asclearly indicatedin Figure 2.

The valve proper includes a compressible plug 16, preferably of theFuller valve type, designed to cooperate with the seat l5 of one of therings and formed for seating engagement with the seat 15 of that ringwhen'the valve is in closed position. The valve plug is secured upon astem 17' which may, for the reception ofv the valve, be reduced andthreaded, as at 18, and the plug held in position by a metallic cap ornut 19 threaded on the reduced end of the stem. The stem extends throughthering with which the valve plug is designed to cooperate and isprovided remote from the valve plug with an annular collar 20 having adiameter appropriate to insure a substantial sealing, slidingcooperation with the interior of the valve body 1.

Beyond the collar 20 the valve stem isextended Y as a diametricallyenlarged section 21 having a reduced and threaded at 23 for thepractical coupling thereto o! a supply pipe. The opposite end of thesleeve has a flange 24 which overlies and bears upon both the ange 14 ofthe ring at that end of the body and the similar end of the body.

it being understood that when the rings 13 are in position inthe body,their relatively outer `lsuri'aces are flush with the respective ends ofthe body.

A clamping nut 25 engages the threaded ends of the body having aninwardly extending flange 26 to overlie the flange 24 of the sleeve 22,vthe nut 25 cooperating with the threads on the end of the body and, ildesired, a flexible gasket 27 may be interposed between the flange 24 ofthe sleeve 22 and the overlying portions of the ring and body 1 to sealthe connection. The ring 13 at the end of the body opposite the valve isrigidly secured in place by a hollow cap 28 having a lateral ange 29 tobear through the medium of an interposed gasket 30 on the underlyingring 13 and the adjacent end of the body 1. A clamping nut 31 isarranged for threaded connection with the threads 2 at this end of thebody and has a flange 32 to overlie the flange 29 of the cap and securethe parts in xed relation.

'In this connection, it is to be noted that the cap prior to the seatingof the nut 31 may be turned to any desired position, as this capabilitytends 'to a desirable result in connection with the structure as aWhole. The cap 28 is provided with upstanding, spaced ears 33, and thediametrically enlarged extension 21 of the valve st em is of such lengththat when the parts are in connected relation this steml extends throughan opening 34 in the cap and above the latter between the ears 33. Acylindrical section of appropriate sealing material 35 encircles thevalve stem extension 21, resting between the upper end of the cap 28 andthe ring 13, so that when the nut 31 is tightened, a sealing juncture iseffected to prevent leakage around the valve stem extension.

The valve is moved to open position through the medium of an operatinglever 36 appropriately formed at one end as a handle 37 and providedadjacent its opposite end with a circular enlargement 38 which, throughthe medium of a pivot pin 39, is mounted eccentrically between the ears33. The pivot pin is formed for convenient removal as, for example,provided at one end with a head and at the opposite end with a removableconnector to prevent accidental separation of the pin. The circularenlargement 38 presents a relatively broad bearing surface 40 whichrests upon the upper end of the valve stem extension 21, and theeccentric mounting of this enlargement is such that when the handle endof the lever is depressed, the enlargement riding upon the upper end ofthe valve stem extension 21 depresses such valve stem to an extent topermit the valve to be forced to an open position. The operating lever36 is extended beyond the enlargement 38, as at 41, and terminallyformed with an opening 42 so that this extension 41 of the lever isoperated in a direction opposite the movement of the handle end of thelever in the unseating of the valve.

The valve with the partsconnected and arranged as described is appliedabove the conventional toilet 43 through the medium of the plate 9which, oi' course, is connected to an appropriate fixture. The servicepipe 44 for the water is connected to the end 23 of the sleeve extensionJ 22. An outlet pipe 45 is connected to the outlet 8 of the body andleads to the bowl of the toilet and there connects with'y any desiredform of nozzle or spray, indicated at 46, for the delivery -of the waterwith a proper whirling motion and in proper quantity for the flushingoperation. The opening 42 in the operating lever extension is connectedby a rod 47 to the usual dump pan 48 so that as the lever is operated toopen the valve, the dump pan is moved to an .open position so that theflushing operation of the watercreates an effective discharge.

An important feature of the present invention resides in its completereversibility in order that a standard valve construction may be readilyadapted for use with toilets of this character arranged in differentpositions and, therefore, requiring reverse locations of the valve. Forexample, in some installations the Ibovvl is so ar. ranged that thevalve support is at the left 'of the bowl and in other installations thevalve support must be at the right of the bowl in order to adapt thevalve to the bowl and to the adjacent fixture from which the valve mustbe supported. Ordinarily, it is necessary to have valves with reverselyarranged securing means and cooperating parts in order to secure thisresult, while with the present invention this disadvantage is overcome.

It is. quite apparent from the above description that all parts arecompletely reversible, that is, the clamping nuts and rings 13 may beremoved from the valve as well as the valve stem and valve plug, and thevalvestem and plug completely reversed, cooperating with the oppositeend of the valve body, which will place the plate 9 on the opposite sideof the valve body and thus permit or adapt the valve for securing it ineither of these desirable positions. Of course, the plate may be securedin any rot'ative position with respect to the body and the completerevoluble adjustment of the cap 28 before it is secured in positionpermits the disposition of the handle 36 in any proper desired relationto the plate 9 so that the valve may be secured in position and thehandle placed in the most convenient relation to the valve foroperation.

As the ring 13 carried by the valve stem is in effect not removable fromthe stem, of course any reversal of the valve requires the removal ofthe remainingring 13, the complete reversal of the valve stem, valve andring and the application of the free ring to the opposite end of thebody. The extension 22 and also the cap 28 may obviously be applied toeither end of the body so that a complete reversal of the valve and itsparts is readily effected. Thus a standard valve may be provided for allequipments and the valve parts assembled as necessary in order to permitthe securing of the valve to the xture in the proper position.

A further and essential feature of the valve is the simplicity withwhich the interior parts thereof may be removed for repair orreplacement without disturbing the valve connection. Obviously throughthe removal of the sleeve 22 following the removal of the nut 25, theentire valve assembly may be removed from the body, and this is alsotrue of the valve operating lever and cap connection and this withoutdisturbing the outlet pipe 45 or the connection of the body 1 to thefixture. 'Ihus the valve may be readily and conveniently repaired,repacked or any part thereof may be readily replaced without disturbingthe valve connection. This is an important feature because where suchvalves require replacement or repacking, it is oi' essential importancethat the operation be carried out speedily in order that the use of theapparatus may not be interrupted for any considerable time.

The collar 20 is preferably formed with an opening 49 extendingtherethrough, and it is to be noted that when the valve is in closedposition there is a space 50 between the collar 20 and the overlyingring 13. When the valve is opened', a portion of the incoming waterpasses through the opening 49, accumulating in the space 50 between thecollar and the ring 13, and serves as a cushioning means for the closingmovement of the valve, thus permitting the valve to move to its seatslowly and with no appreciable jar or impact.

Of course, it is to be understood that the various parts of the valveare made of appropriate material and in appropriate size for the workfor which they are designed, and in this connection no restriction is tobe understood either as to size or material either in the valve parts orin the operating means therefor. Of course, as the valve is opened toadmit the ushing water, the pan is also dumped, as is conventionallyrequired in valves of this type.

Having thus described the invention, what is claimed as new, iszl.
